IMPROVEMENT IN THE MANUFACTURE 0F IRON BY THE ELLERSHAUSEN PROCESS.

Specification forming part of Letters Patent No. 104,939, dated July 5,1870.

To all whom it may concern:

Be it known that I, HENRY DAVIES, of Newport, in the county of Campbelland State of Kentucky, have invented a new and useful Improvement in theManufacture of Iron 5 and I do hereby declare that the followin g is afull, clear, and exact description thereof, which will enable othersskilled in the art to make and use the same, reference being had to theaccompanying drawing, forming a part of this specification.'

This invention relates to improvements in the manufacture of ironaccording to what is known as the Ellershausen process 5 and consists inan arrangement of mixing-table, molten-iron ladle, and ore-feedingapparatus, whereby the mixture of ore or earthy matter with the moltenmetal can be made in exact and predetermined proportions, as hereinafterspecified.

Figure l is a side elevation of improvedmachine, partly taken out. Fig.2 is a sectional elevation of the ore-feeding apparatus, and Fig. 3 is aplan view.

Similar letters of reference indicate correspondin g parts.

A is a large circular table for the reception of the molten metal andthe ore to be mixed. This table is arranged to revolve in a horizontalplane under the declining spouts for the substance to be mixed, and isdivided into two or more channels on the top by vertical ribs I3, andthese are divided again into sections .by the transverse rib C.

D is a hopper above the table A, into which the pulverized ore or earthymatter is placed for feeding down upon the table. This hopper has asmany feeding-orifices E in the bottomas there are channels in the top ofthe table, and the feeding-spout F, leading therefrom, also has asimilar number of channels, and each orifice E has a cutting-oft' slideor gate. Below the cutting-off gate is a feedroller, G, withcorresponding` spaces or channels divided transversely for the receptionof the ore and delivering to the spout below.

B2 is a hopper or ladle for feeding the molten metal to the table formixing with the ore. It is made in the form of a hollow sector of acircle, and journaled at the axis I of the said circle. The top K andthe bottom L represent radial lines, and the sides M are parallel, whilethe back N represents the section of a circle. At the mouth it isnarrowed down on the curved lines O, Fig. 3, and these narrowing wallsare also curved in the plane of the circle of the ladle, and on the sameaxis as shown in Fig. 1.

The object of this construction is to cause the ladle to pour the samequantity of metal to every inch it is raised on its axis, whether at thebeginning or at any other part of the pourin gs. It is necessary tonarrow down the mouth of the ladle, to prevent the flow therefrom beingso thin as to chill and not run free.

The rear part of the ladle has chains P connected to the lower part, andattached, by their other ends, to the spirally-grooved rollers Q in thetop of the frame.

The connection of the ladle to the axial bar I is such that it may -beadjusted from side to side thereon for pouring into either of thechannels of the table A.

The winding-drum Q is connected, by the reducing-gears Q1, Q2, Q3, andQ4, with the driving-shaft It, connected with the main drivingshaft S,which also drives the table by suitable driving-wheels, by the belt T,and suitable pulleys, and the feed-roller G is connected, by wheels G1G2, shaft G3, belt G4, and suitable pulleys, with the samedriving-shaft.

Fast and loose pulleys are provided for the belt G4, so that thefeed-roller may be set in motion at the right time after the table andthe ladle have been started. The ladle is raised, by the drum andchains, on its axis, to pour the metal upon the table.

It will be seen that the hopper and the ladle bein g charged with theirrespective substance, andthe machine being set in operation, thedelivery of each will be in exact proportion to the other, no matterwhether it moves fast or slow, and, by the proper calculations,arrangement, and adjustment of the speed, any required predeterminedmixtures may be effected. The driving gears of either the table,feedroller, or ladle may have dierential charge apparatus for effectingany modifications required of the proportions.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A tilting` ledle constructed and arranged ordelivering a. uniform quantity of metal, when tilted at a uniform reteof speed, substantially in the manner herein shown and described.

2. The eo1nbi1mtion,witli arot-ating or other receiving-table, of theore-l1opper and feeding Wheel, and the tilting ladle7 arranged foroperating relatively to each other, substantially as specified.

3. The arrangement of the ladle for adjustlnent along, itsaxis,substantia1ly as speeited.
